PA.X.C — One Engine Inoperative (Simulated) (solely by Reference to Instruments) During Straight-and-Level Flight and Turns

What does ACS code PA.X.C cover?

ACS Code PA.X.C covers "One Engine Inoperative (Simulated) (solely by Reference to Instruments) During Straight-and-Level Flight and Turns" under Area of Operation X (Multiengine Operations) for the FAA Private Pilot Airplane certificate (FAA-S-ACS-6C). Candidates are tested on knowledge elements and risk management factors defined in 14 CFR regulations and FAA handbooks (PHAK / AFH).

Airman Certification Standards Elements

Knowledge Elements

• PA.X.C.K1: Procedures used if engine failure occurs during straight-and-level flight and turns while on instruments.

Risk Management Elements

• PA.X.C.R1: Identification of the inoperative engine.
• PA.X.C.R2: Inability to climb or maintain altitude with an inoperative engine.
• PA.X.C.R3: Low altitude maneuvering, including stall, spin, or controlled flight into terrain (CFIT).
• PA.X.C.R4: Distractions, task prioritization, loss of situational awareness, or disorientation.
• PA.X.C.R5: Fuel management during single-engine operation.

How do I study PA.X.C?

1. Read each element for PA.X.C in FAA-S-ACS-6C and note any you cannot explain in your own words.
2. Study each one in the FAA source it points to: the handbook chapter, the 14 CFR section or the AIM paragraph.
3. Practice with questions tagged PA.X.C, and read the explanation for every miss.
4. Retest, then review the ACS codes you still miss on your practice test report.
